Description Christian Wissel 2021-04-28 15:34:08 UTC

Description of problem:
rlwrap has a built-in debug log, IF compiled with debug enabled, as describe here https://github.com/hanslub42/rlwrap/blob/master/BUGS
This causes rlwrap to write a debug log in /tmp/rlwrap.debug on invocation.

This log is not deleted on exit and can't be written to by other users who might be running rlwrap, due to default umask of 0022 creating the file with 0644 permissions.

Version-Release number of selected component (if applicable):
rlwrap-0.44-1.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. invoke rlwrap as user 1
2. invoke rlwrap as user 2

Actual results:
rlwrap: error: Cannot open  debug log /tmp/rlwrap.debug for appending: Permission denied


Expected results:
no error

Additional info:
Possible workarounds:
- Change umask to 0002, if users are in a common group
- Leave the debug log in place and change its permissions to 0664 or 0666.
